Sidebar session title display (auto-generated "Recents" titles)

Current Documentation

Summary

Currently, session titles in the left sidebar ("Recents") are auto-generated
by Claude Code, but even when the entire conversation is in Japanese, the
generated title is often still in English.

Request

Please allow auto-generated session titles to be displayed in Japanese

when the conversation language is Japanese (or based on a user language
setting).

Additionally, it would be great to have a toggle/button on each session

title to switch between the original (e.g. English) title and a
Japanese-translated version.

Motivation

Japanese-speaking users currently see a mix of English and Japanese titles
in the sidebar, which makes scanning session history harder. This seems
like a relatively small, high-value UX improvement.

What's Wrong or Missing?

Session titles in the left sidebar ("Recents") are auto-generated by
Claude Code, but even when the entire conversation is conducted in
Japanese, the generated title is still often shown in English. This
makes it harder for Japanese-speaking users to scan their session
history at a glance.

There is currently no setting or button to display these auto-generated
titles in Japanese, nor any way to toggle between the original title
and a translated version.

Suggested Improvement

Add a setting (and/or a per-title toggle button) that lets users display
auto-generated session titles in Japanese:

When generating a session title, detect the conversation language and

generate the title in that language (e.g., Japanese conversations get
Japanese titles).

Add a small toggle/icon next to each sidebar title that switches

between the original title and a translated Japanese version, similar
to a "translate" button.

Optionally, add a global preference (e.g., in settings) to choose the

default language for auto-generated titles, independent of the
conversation language.

Example: a session conducted entirely in Japanese currently shows
"Left sidebar latest items Japanese localization" in the sidebar. With
this change, it could instead show "左サイドバー最近の項目の日本語化"
automatically, or offer a toggle button to switch between the two.

Impact

High - Prevents users from using a feature

Additional Context

Screenshot: See attached image of the left sidebar showing a mix of
English auto-generated titles (e.g. "Left sidebar latest items Japanese
localization") alongside a Japanese section header ("最近の項目"),
even though the conversations themselves were conducted entirely in
Japanese.

Similar examples: Some chat/AI tools (e.g. certain note-taking or
translation apps) offer a small "translate" icon next to auto-generated
titles/summaries, allowing users to toggle between the original and a
translated version without losing the source text.
